Abstract
Abstract 4,5-Dihydro-4,5-dimethylene-1-phenyl-1,2,3-triazole ( 4 ), the 1,2,3-triazole analogue of o -quinodimethane, can be generated in situ from 4,5-bis(bromomethyl) derivative ( 3 ) by sodium iodide induced 1,4-elimination process. By trapping the 1,4-dimethylene-triazole with symmetrically and unsymmetrically substituted dienophiles the Diels-Alder cycloadducts were isolated in moderate to low yields; in the presence of activated molecular sieves the yields are markedly improved.
